Description
(1) technical field:
The present invention relates to a kind of frequency shunt, particularly a kind of frequency shunt that has preceding stage coupling unit, this frequency shunt can be made with high-temperature superconducting thin film.
(2) background technology:
Frequency shunt is a microwave, a kind of important passive device of RF application, particularly play an important role in the multichannel receiving system in communication system, its effect is carried out frequency division with the wide frequency domain signal that receives according to certain frequency range exactly, make the signal of different frequency range be sent to corresponding channel separately, export by output port separately behind the channel filter filtering, by the transmission of signal in splitter, finish the function treatment of frequency-division filter to received signal, making the signal that is transferred to each output port of splitter is the signal of regulation frequency range, and the device that offers next stage carries out signal processing.
High temperature superconductor technology is after finding high temperature superconducting materia the eighties, particularly in a fast-developing high-tech technology of getting up in recent years, the high-temperature superconductor electronic technology especially has boundless application prospect in radio frequency, microwave communication field, super conductive filter is ripe in the application of moving communicating field, realized at present the small lot sizable application of high temperature superconduction wave filter, realized that in China the actual of high temperature superconduction wave filter be incorporated into the power networks in the U.S..Because high-temperature superconducting thin film has the sheet resistance of being almost equal to zero, have very high quality factor (Q value), so microstrip filter that adopts high-temperature superconducting thin film to make, have extremely low pass-band loss and high adjacent interference rejection capability frequently, be applied on the receiving system of mobile communication base station, show as the receiving sensitivity of improvement system, improve the antijamming capability of system.Mobile communication base station uses after the high temperature superconduction wave filter, and area coverage, raising power system capacity, the adjacent frequency of reduction that can increase the base station disturb raising speech quality; And can reduce the transmitting power of mobile phone, reduce the influence of electromagenetic wave radiation to human brain.
Equally, high temperature superconductor technology is applied to carry out in the design of the frequency shunt that frequency-division filter handles, the performance advantage of product is obvious equally.In the research work of high-temperature superconductor splitter, scientific and technical personnel carried out respective design work both at home and abroad, and present technical scheme also has various ways: adopt circulator to add the scheme of channel model group; Adopt the linear matched network to add the technical scheme of channel model group; Adopt 90 ° of hybrid circuits to add the scheme of channel model group.
Accompanying drawing 1 is the typical scheme that adopts circulator to add the channel model group, in this project organization, introduce the circulator of three ports, frequency signal can only transmit along the direction of arrow, and input signal comprises the frequency of f1, f2, f3, the signal of f1 via first circulator after, leach by first channel model, the f2 signal is leached by second channel model, f3 via second circulator after, continue to transmit downwards.
Accompanying drawing 2 adds the technical scheme of channel model group for adopting the linear matched network, in this structure, it is one fen splitter that comprises three channels of three, operation principle is that the characteristic impedance and the electrical length of regulating the branch line that channel model links to each other in each the joint transmission line of splitter neutral line matching network and the splitter reach rational coupling, this method is simple and size is little, and coupling is very difficult but practical application is got up.
Accompanying drawing 3 adds the scheme of channel model group for adopting 90 ° of hybrid circuits, what accompanying drawing showed is the splitter that comprises 2 pairs of 90 ° of hybrid circuits, the shortcoming of this programme is to have introduced 90 ° of hybrid circuits, each channel needs two identical channel models, also matched load to be arranged simultaneously, increased the area of substrate, be unfavorable for that miniaturization is integrated.
